Celebrate Halloween with costumes, trick or treating, smashingly fun science and more!

Two weeks of family-friendly science experiences will let you get into the Halloween spirit. Our limited capacity, timed-entry tickets and other protocols allow for plenty of space and comfort for a scary good time indoors.

Explore a specially decorated exhibit with a “Scary Storage” look at the Museum’s curiosities, take part in physically distanced trick-or-treating, and examine the science of Halloween with pumpkin drops, slime, eyeballs and chilling laboratory sessions.
